Design concepts for laminated composite materials with thermal and/or mechanical coupling response

TL;DRAbstract

New design concepts are demonstrated for twenty-four classes of laminate, which have been derived as part of an ongoing study on the development of a unified approach to the characterization of coupled laminates. This article presents a description of each class of coupled laminate; the vast majority possessing coupling behaviour not previously identified in the literature. Coupled laminates have potential applications in the: design of aero-elastic compliant rotor blades or aircraft wing structures, by introducing tailored Extension-Twisting and/or Shearing-Extension coupling at the laminate level or; design of thermally activated morphing structures, by exploiting more complex coupling behaviour. Results are presented which demonstrate various mechanical coupling responses, including thermally induced curvature predictions resulting from a high temperature cure process. However, the main focus of this article concerns the identification of laminates possessing complex mechanical coup
